About this map

Long Valley Creek defines the low-lying corridor of this high-desert landscape, where the Western Pacific Railroad snakes along the base of the Fort Sage Mountains. In the late 1970s, this area of Lassen County serves as a transition point between the timbered slopes of the Plumas National Forest and the arid valley floor. Small settlements like Omira and Constantia dot the rail line, representing the sparse but persistent ranching and transit outposts of the region.

The presence of an Old Railroad Grade and numerous Jeep Trails indicates the evolution of transport through this corridor, connecting the valley to the higher elevations of the Diamond Mts. Notable landmarks such as Zamboni Hot Springs and the Eagles Peak Ski Area suggest the land's utility for both geothermal features and seasonal recreation. High peaks like Adams Peak and Seven Lakes Mountain anchor the western and eastern horizons, providing a clear view of the complex terrain that straddles the California and Nevada border.
